for Siko

in my wood I'm sure they simply  rot,

the same in pots, no matter the soil mix or composition

some may show small wounds and then rot,

sometimes ,  rotting ring appears at the base of the stem and the stem falls

even if I dig the tuber at once and clean it, it will rot in few days;

my opinion is that I have too many fungi and mildews here all over my garden and woods around


p.s.
I lost a lot of Pinellias ( pedatisecta expecially ) always rotting in late spring, when the temperature begins to increase:
the clumps look fine but  some of them begin to rot in the centre and then the whole clump will have problems
and those tubers are softened and have a very bad smelt, leaving a milky liquid 
when I crush the tuber between the fingers
